A pump is required to deliver water from a reservoir to a water tower. A minimum of 500 gpm is
required to supply the water tower storage tank 150 ft above the reservoir. Use 6" diameter commercial
steel pipe (ε = 0.00015 ft). For the piping system K = 15 and K = 1.0. The suction side pipe length is
50 ft, and the discharge side pipe length is 5,000 ft. Atmospheric pressure is 14.7 psi and vapor pressure
is 0.256 psi. The viscosity is 2.34 x 105 slug/ft-s. The pump centerline will be 5' above the supply
reservoir water surface. Using a pump from Gould's Pump Selection System do the following.
a. Find the operating point of the pump (Q, H₂).
b. Find the impeller diameter.
c. Find the NPSHR
d. Find the NPSHA
